He's Afrikaner. They are evil AND nuts.

J.B.M. Hertzog founded the National Party in 1914 in order to rally Afrikaners against what he considered the Anglicizing policies of the government of Louis Botha and Jan Christian Smuts. In 1924, after mild attempts to relax the colour bar, the Smuts government was defeated by a Nationalist-Labour coalition led by Hertzog, who in two terms sought to further emancipate South Africa from British imperial control and to provide greater “protection” for the whites from the Black Africans and for the Afrikaners from the British. From 1933 to 1939 Hertzog and Smuts joined a coalition government and fused their respective followings into the United Party. Some Nationalists, led by Daniel F. Malan, however, held out and kept the National Party alive and, in 1939, reaccepted Hertzog as their leader in a reorganized opposition party known as the Re-united National Party, or People’s Party (Herenigde Nasionale Party, or Volksparty). The new party was weakened by wartime factionalism; and Hertzog and others with Nazi sympathies eventually walked out and formed the Afrikaner Party (1941).

The Re-united National Party returned victoriously in the 1948 elections and subsequently enacted a mass of racial legislation that was designed to preserve white supremacy in South Africa; the National Party named its policy “apartheid.” The party went on to consolidate its power, absorbing the Afrikaner Party in 1951. It renamed itself the National Party of South Africa (1951) and gradually augmented its control of the House of Assembly—from 73 seats in 1948 to 134 seats (81 percent) in 1977. The party was led successively by Daniel F. Malan (1948–54), Johannes Gerhardus Strijdom (1954–58), Hendrik Frensch Verwoerd (1958–66), John Vorster (1966–78), P.W. Botha (1978–89), F.W. de Klerk (1989–97), and Marthinus van Schalkwyk (1997–2005). The National Party also broke South Africa away from the Commonwealth, making it a republic in 1961. From the premiership of Vorster on, the National Party attempted what it termed an “enlightened” (verligte) policy on the race question; but this meant hardly more than speeding up the formation of Black “homelands” and alleviating—selectively—some of the apartheid policies found inconvenient to general economic and cultural development.
